couplings which are designed to effect an automatie coupling, as thecars come together, by

means of gravity-hooks, and which are adapted to be uncoupled from thesides or top of the car without the necessity of going between the same.

The object of my improvements is to provide a simple and improvedautomatic coup- 2O ling of this class which will possess advantages inpoint of inexpensiveness and durability of construction and convenienceand efficiency in operation.

In the drawings, Figure l is a perspective view of a draw-head embodyingmy improvements. Fig. 2 is a front view of the same, showing it inposition upon the end of a car. Fig. 3 is avertical longitudinalsectional view taken centrally through the draw-head. Fig. 4 is acorresponding view taken through the chamber which receives thecoupling-hook of an adjoining draw-head. Fig. 5 is a side elevation, theside of the drawhead being re moved or broken away. Fig. 6 is a verticaltransverse sectional view taken through the fulcrum of thecoupling-hook. Fig. 7 isa corresponding view taken on the plane of thebar or rod by which the hook is operated to uncouple.

Corresponding parts in the figures are denoted by the same letters ofreference.

Referring to the drawings, A designates the draw-head, which may besecured to the end of the car Bin any suitable manner, by which 4 5 itis adapted to perform the office of a bumper. In the front of thedraw-head is provided a central chamber or recess, A and a verticalperforation, a, adapted .to receive a vertical coupling-pin, O, by whicha coupling may be 5o effected with a draw-head of the ordinarypinand-link construction, and from this recess extends a longitudinalcentral perforation, a which receives the bar D, by which the drawheadis connected to the car, the head cl of the bar being accommodated inthe said recess. In one side of the draw-head is formed a verticalchamber or recess, A", having the open mouth provided with an inclinedbottom, a the bottom of the recess in rear of the said in clined mouthbeing also preferably inclined 6 downwardly and rearward] y, as shown.

E designates a transverse horizontal coupling-pin,which is disposed inrear of and just above the inclined bottom a, and is adapted to beengaged by the coupling-hook of an ad 6 joining draw-head as the carscome. together. This pin is also preferably disposed so as to supportthe front end of the gravity-hook at the other side of the draw-head andretain it at a proper elevation to effect an automatic o coupling.

F designates the gravity-hook, which works in a longitudinal verticalchamber or recess, A", provided in the side-of the draw-head oppositefrom the chamber A, and projects from 7 5 the mouth of the same. Thehook comprises a main portion, having the hook-shaped front end, f,provided with the beveled front f, and with a curved recess, f adaptedto receive the transverse pin E, and a rear arm or por- 8 tion, F whichis at an angle to the main portion, and is preferably formed smallerthan the latter to form a shoulder, f near which is provided a crosspin,G, forming the fulcram of the hook. This pin has its bearing 8 at oneside in a horizontal longitudinally-extending slot, g, formed in thecentral wall of the draw-head and in rear of the chamber A while itsother side bears in a corresponding slot, in the side of the draw-head.is obvious that by this arrangement, when the fulcrum of the hook is atthe front end of its bearing-slot the hook will automatically enter thechamber A of an adjoining drawhead as the draw-heads come together, andthis effect the coupling. It is also obvious that this arrangementenables the hook to be slid back in the chamber A the limit of the saidbearing-slot, so that it will be out of the way when it is desired toeffect a coupling by 109 means of the ordinary pin-and-link-mechanism,this position being illustrated in dotted lines, Fig. 5.

The operation of uncoupling is effected by means of a vertical bar orrod, H, arranged to slide through a perforation, 'h, in the top of thedraw-head, and extending preferably to the top of the car, so that itmay be readily operated from that point. At the lower end of the bar isprovided an eye, H, which receives the rear arm, E of the hook, andslides in a vertical groove, h formed in the inner wall of the chamberA, and preferably at the bot-tom of the same, from which it is apparentthat by depressing the said bar the front end of the hook is elevatedfrom its engagement with the pin E of the adjoining draw-head, and themechanism is uncoupled. The bar H may be conveniently operated from thesides of the car by means oflevers I I, fulcrumed upon the end of thecar and pivotall y connected to the bar. Thehook is locked in positionby means of a locking-plate, J, pivoted upon the side of the draw-head,and having recesses or notches jj in its und er edge, respectivelyadapted to engage the projecting end of the fulcrum-pin G when it is atthe front or rear end of its bearing-slot. This plate may be elevated todisengage it from the fulcrum-pin and permit of the adjustment of thelatter in the slot. A cam-plate, K, is preferably fulcrumed upon theside of the draw-head and acts upon the curved end j of the plate J tolock the same into engagement with the fulcrum-pin.

I claim as my invention- 1. The combination, as an improvement inear-couplings, with a draw-head embodying coupling mechanism andprovided with the link chamber or recess at its front and the veiticalpin-perforation, and having the longitudinal central perforationextending from this recess, of the connecting-bar extendinglongitudinally through the corresponding perforation and having its headaccommodated in the recess, substantially as set forth.

2. As an improvementin car-couplings, the draw-head comprising sidechambers and provided with the central front recess having the verticalperforation adapted to receivea coupling-pin, the coupling-hook arrangedin one of the side recesses and having a longitudinally-movablefulcrum,whcreby the hook may be set back in its chamber, and means forlooking the fulcrum of the hook in the position to which it has beenadjusted, substantially as set forth.

3. As an improvementin car-couplings, the combination, with a draw-headhaving a vertical recess or chamber at each side, in one of which isfulcru'med a gravity-hook, of the horizontal transverse coupling-pinextending through both chambers and under the hook and supporting thefront end of the latter to retain it at the proper elevation to effectan automatic coupling, substantially as set forth.

4. The combination, with the draw -head having the vertical longitudinalchamber or recess and the horizontal longitudinally-disposedbearing-slot, of the gravity-hook normally projecting from the mouth ofthe chamber and having itsfulcrum-pin adjustable in the slot,substantiall y as and for the purpose set forth.

5. The combination, with the drawhead, having the vertical longitudinalchamber having the longitudinally-extending slot in the inner wall ofthe same and the corresponding slotin the side ofthe draw-head,of thegravityhook having the transverse fulcrum-pin bearing in these slots andprojecting from the side of the draw-head, and the pivoted lockingplatehaving the notches for engaging the pro jecting end of the pin,substantially as and for the purpose set forth.

6. The combination of the draw-head having the vertical longitudinalchamber, the perforation in the top thereof, andthe longitudinallydisposed bearing slot, .the couplinghook having its fulcrum-pinadjustable in the said slot, the vertical operating-bar working throughthe said perforation and having an eye at its lower end to receive therear end of the hook, and means for locking the fulcrumpin in theposition to which it is adjusted, substantially as and for the purposeset forth.

An improved car-coupling comprising the draw-head having the sidechambers, the perforation in the top, the longitudinally-extending innerbearing-slot, the corresponding slot in its side, and provided with thehorizontal transverse coupling-pin, the couplinghook fulcrumed in one ofsaid chambers and having its fu1crum-pin in the slots and pro-
